  • Mystery Deepens: Matter and Antimatter Are Mirror Images

    Matter and antimatter appear to be perfect mirror images of each other as far as anyone can see, scientists have discovered with unprecedented precision, foiling hope of solving the mystery as to why there is far more matter than antimatter in the universe. Everyday matter is made up of protons, neutrons or electrons. These particles have counterparts known as antiparticles — antiprotons, antineutrons and positrons, respectively — that have the same mass but the opposite electric charge. (Although neutrons and antineutrons are both neutrally charged, they are each made of particles known as quarks that possess fractional electrical charges, and...

    Physicists find ways to increase antihydrogen production 18 hours ago by Lisa Zyga feature Antihydrogen consists of an antiproton and a positron. Credit: public domain (—There are many experiments that physicists would like to perform on antimatter, from studying its properties with spectroscopic measurements to testing how it interacts with gravity. But in order to perform these experiments, scientists first need some antimatter. Of course, they won't be finding any in nature (due to antimatter's tendency to annihilate in a burst of energy when it comes in contact with ordinary matter), and creating it in the lab has proven to...

    The new Majorana particle showed up inside a superconductor, a material in which the free movement of electrons allows electricity to flow without resistance. The research team, led by Ali Yazdani of Princeton University, placed a long chain of iron atoms, which are magnetic, on top of a superconductor made of lead. Normally, magnetism disrupts superconductors, which depend on a lack of magnetic fields for their electrons to flow unimpeded. But in this case the magnetic chain turned into a special type of superconductor in which electrons next to one another in the chain coordinated their spins to simultaneously satisfy...

    Exotic particles called neutrinos have been caught in the act of shape-shifting, switching from one flavor to another, in a discovery that could help solve the mystery of antimatter. Neutrinos come in three flavors — electron, muon and tau — and have been known to change, or oscillate, between certain flavors. Now, for the first time, scientists can definitively say they've discovered muon neutrinos changing into electron neutrinos. The discovery was made at the T2K neutrino experiment in Japan, where scientists sent a beam of muon neutrinos from the J-PARC laboratory in Tokai Village on the eastern coast of Japan,...

    ( —An international team of physicists working at the University of Michigan has succeeded in building a tabletop antimatter "gun" capable of spewing short bursts of positrons. In their paper published in the journal Physical Review Letters, the team describes how they created the gun, what it's capable of doing, and to what use it may be put. Positrons are anti-particles, the opposite twin of electrons. Besides being created in physics labs, they are also found in jets emitted by black holes and pulsars. To date, the creation of positrons for study has involved very big and expensive machines. One...

But there must be some differences between the two types of matter, they also think, because otherwise matter and antimatter would have canceled each other out completely and there would be no universe. Scientists at CERN are making atoms of antihydrogen to try to pin down what those differences might be. But they're also willing to consider the possibility that the ideas were wrong in the first place, said Joel Fajans, a professor...

    Physicists have long suspected that antiprotons must become trapped in a belt around Earth. Now they've found it. The Earth is constantly bombarded by high energy particles called cosmic rays. These are generated by the Sun and by other sources further afield. (The source of the highest energy cosmic rays is still a mystery). The particles are generally protons, electrons and helium nuclei and when they collide with nuclei in the Earth's upper atmosphere they can produce showers of daughter particles. These showers can be so extensive that they can easily be observed from the ground. Astronomers long ago realised...

    As the 21st century unfolds, radically different forms of air and space vehicles will replace the clunky machines of today, whisking passengers at ultra-high speed around the Earth and outward into space. Laboratories scattered around the world are delving into novel and exotic forms of propulsion. Breakthrough physics could well make possible ambitious human treks across interstellar distances. Work is underway to harness antimatter as a way to shave travel time to the Moon down to minutes, or between Earth and Mars to a day. Meanwhile, laser and microwave technology is rapidly advancing the idea of beaming people and payloads...

    For education and discussion only. Not for commercial use. European scientists say they have created enough antihydrogen — a type of the mirror-image, antimatter stuff that fictionally powers spaceships on Star Trek — to test a widely held basic model of the universe. While antihydrogen has been made before, the more than 50,000 atoms created at the CERN particle accelerator in Geneva are "by far, the most produced," said Jeffrey Hangst, a leader of the ATHENA collaboration, one of two groups of physicists working on antihydrogen at CERN. The quest to understand and manipulate antimatter is one of the most...

    Robert Lull Forward Robert Lull Forward died at home of brain cancer at the age of 70. Forward was born 15 August 1932 in Geneva, New York. After graduation from the University of Maryland in 1954 with a BS degree in Physics and a Second Lieutenant commission in the Air Force, he married Martha Neil Dodson and served two years stateside during the closing years of the Korean War. Upon leaving the service Forward was awarded a Hughes Aircraft Company Graduate Research Fellowship, which he used to obtain a MS in Applied Physics from UCLA in 1958 and a PhD...

    Scientists claim antimatter breakthrough Scientists have announced the first large-scale production of antimatter. A team based at the European Organisation for Nuclear Research in Geneva say they have developed a large amount of the substance. Antimatter is a reverse form of ordinary matter. When the two kinds of matter meet they annihilate each other in an enormous burst of energy. It's this process which provides the power source for Starship Enterprise in its film and TV space adventures. Physicists have made only very small quantities of antimatter before. But the CERN team say they have made at least 50,000 atoms...
